Aluminum Zinc Magnesium has a Young's modulus of 690 GPa, which is greater even than Beryllium. It can, therefore, be used to make extremely-low-dispersion railgun barrels. I was unable to find any reference to an aluminum alloy this rigid anywhere online.
Based on the other mostly-aluminum alloys, and on aluminum itself, I think there's an extra zero. 69 GPa would be a lot more believable.

It seems all the numbers are higher. www.substech.com/dokuwiki/doku.php?id=wrought_aluminum-zinc-magnesium_alloy_7001Perhaps the tech we see in game is based on an assumption that metallurgy in the future will be much better than the present, or that perhaps manufacturing in zero g and/or in vacuum will result in much stronger material than present tech can produce. These numbers are based on a "Annealing" finishing process. Perhaps other future processes can result in a stronger material. It would be interesting to see if all the materials in game are "beefed up" as it were, or just the alloys. |

Based on the other mostly-aluminum alloys, and on aluminum itself, I think there's an extra zero. 69 GPa would be a lot more believable. Nevermind, check this one out. Modulus of elasticity 721 GPa www.substech.com/dokuwiki/doku.php?id=wrought_aluminum-zinc-magnesium_alloy_7005On this site there are at least 7 different Aluminum-Zinc-Magnesium alloys, so perhaps qswitched found a particular alloy mix/ finishing process we are not aware of from some other source. The more I learn about this game, the more impressed I am by the amount of research and time that must have went into it. Perhaps ingame there are (in theory) as really as many as 20 different Aluminum-Zinc-Magnesium alloys, and in real life, different ones would be chosen based on their properties for different applications, but to make it simpler, these alloy properties we see are a composite of the best properties of a series of different similar Aluminum-Zinc-Magnesium alloys. |

At first I thought, "No way."
"How many factsheets are we going to doubt?
But... When I converted the number in "standard" aka American units next to it, 10400 ksi, to metric, I got 71 GPa.
So, I'll keep my eye on the thread.
Thanks.

Keep in mind: young's modulus of metal alloys typically don't go very far from the base metals.

Well crap... That's my favorite armor material.
Bit of it over some rubber and it'll bounce just about any stock projectile
